Columbia Park is a 19-acre county park located on Lake Winnebago at N10340 Calumet Harbor Rd., Malone--about ten miles northeast of Fond du Lac. The park contains a modern 40-unit campground with electrical hookups and restrooms, boat and RV sanitary dump stations, a playground, a basketball court, one enclosed and two open-air shelters, and picnic facilities.

Columbia Park is probably best known for its boating facilities. A 4-slip marina is available for annual rentals, along with overnight docking for another 40-50 boats on 900 feet of harbor wall. Six boat launches and parking for 100 cars and trailers are available. A 70-foot observation tower and navigation beacon marks the harbor entrance.

Columbia Park is watched over by part-time campground hosts. The campground hosts assist campers in making online reservations for campsites, shelters, and the hall. They also are points of contact for boat slips, docking space and launch passes.
